VACUUM SAND-SETTLING DEVICE.

Application filed. August 18, 1924. Serial N10. 732,819.

To all 'whom t may concern:

Be it known that I, HowAnn B. BLAN'roN, a citizen of the United States, residing at Iowa Park, in the county of lVichita and State of Texas, have invented certain new and useful Improvements in Vacuum Sand- Settling Devices, of which the following is a specification.

This invention relates to pumps and refers more particularly to an attachment to oil well pumps having in combination a gas anchor with perforations and sand settling chambers.

The primary object of the invention being to separate the sand from the oil by depositing the sand in the bottom of the device and allowing only a minimum of sand to pass upward with the oil.

A further object of the invention is to provide a device of this character which will be simple of construction and from which the deposits of sand may be readily removed when desired.

Features of the invention are that by the peculiar arrangement of the different elen'lents, thelife of the pump is prolonged and the utility thereof increased.

Other objects and features as well as those above set forth will be described more in detail in the following explanation of which the accompanying drawings form a part, and in which Figure 1 represents a longitudinal sectional view of the invention.

Figure 2 shows a view partly in section, of the oil inlet member of the pump.

Figure 3 is a side elevational view of the invention with parts broken away.

VFollowing the igures, 1 represents the lininip piston, 2 and 8 are ball valves of standard construction. This piston is adapted to move in the pipe or tubing 1a.

This tubing is attached by suitable collars 7 to a second section of tubing 8 within which are liournaled inlet elbows l in attachment to downwardly extending pipes 1a.

Below this second section of tubing a third section 5 is attached by means of collar 6, a closure member 6 is threadedly engaged in the bottom of the last section` upward through the valves 2 and 3 and so one to the surface of the ground or to tanks located above the surface. The lower ends of the pipes 4a are secured to the walls of the tubing by brackets 8a. A represents the threads at each end of each of the tube members,

It should be understood that the members of the invention may vary somewhat in form and arrangement than that shown in the drawings without departing from the spirit and intent of the invention as set forth in the following claims.

1. In an attachment for oil pumps and the like, a gas anchor with perforations and a sand settling chamber, said attachment having a plurality of casings or tubings, means for joining said casings or tubings in alinement, means in the upper tubing to create a suction in the tubing attached to the iirst tubing, valves in the first tubing, ports in the second tubing in alinement around the periphery of the tubing,I downwardly extending pipes in the second tubing in attachment to the ports to direct liquid passing therethrough in a downward direction, and a third tubing in attachn'lcnt to the second tubing, and means for adjustably closing the lower end of said tubing.

2. In an attachn'ient for oil pumps and the like, a pair of tubular members attached in alinement one to the other, and arranged and adapted to be attached to the tubing of a well pumping apparatus at the extremity thereof, ports in one of the said tubular members, pipes in attachment to these member ports, and extending downwardly in said tubular member, and an adjustable closure member in the bottom of the lower tubular member, substantially as described.

8. In a device of the character described, a pair of tubes, adapted to be adjustably secured one to the other, means for attaching` the assembly of said tubes to the extremity of the tubing' of an oil well pump ing apparatus, ports in the upper tube, and

pipes in attachment to these ports, said pipes extending downwardly in the tube, 10 and a closure member adapted to be threadedly secured in the lower tube.

In testimony whereof I have signed my name to this specication.

HOIVARD B. BLANTON.
